WHERE TO PLANT.

the captive airhiis raised the temperature of its captor by sev- 

 eral degrees, so that its frosty quality is lost. 



But if the cold wave comes quietly and by stealth, as it 

 were, and creeps slowly over the water, it chills the warm vapor 

 and so reaches the south as cold as when it left the north shore. 



Besides this, it has been clearly proved that frost, like wind 

 storms, travels in streaks, often with clearly defined margins, so 

 that a grove that may escape one frost may be touched by an- 

 other less severe, apparently "without rhyme or reason." 



And so, after all the best protection a grove can have is from 

 a belt of timber land, either inclosing it entirely, or else guard- 

 ing it on the north or west, since these are the quarters whence 

 come the highest and coldest winds. 



This is a shield that can happily be obtained iu almost auv 

 locality in Florida, for nearly CA'ery settler takes his land at first 

 or second hand, and forest land still predominates throughout the 

 State ; nowhere do we find immense contiguous tracts of land all 

 cleared and under tillage as in the older settled States.
